Just noticed this while looking up strategy guides for GTA 5.
If you go to the website - you will see the guide is priced at $27 - but then when you go to exit without purchasing, they offer it to you for $17.
That is $10 off. It includes the strategy guide, walkthrough, and other bonuses for the game. If any of you are GTA 5 players, you may like it.
Cheers
